COMBINING LANTERNS AND LAMPS.

Specification of Letters Patent No. 5,516, dated April 18, 1848.

To all whom it may concern:

Be it known that I, JAMES STANLEY GRIMEs, of Lansingburg, in the countyof Rensselaer and State of New York, have invented a new and usefulLantern-Lamp, which I denominate Grimess Tunic Lantern-Lamp and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings ofthe same, making part of this specification, of which- Figure 1, is aperspective view of-the instrument when it is used as a lamp. Fig. 2, isa perspective view of the same when converted into alantern. Fig. 3, isan elevation of the slotted tunic. Fig. 4, is an elevation of amodification of the instrument as a lamp. Fig. 5, is a vertical sectionof the same as a lantern. Fig. 6, is a sectional view showing theconnection of the vertical and horizontal grooves on the lamp.

The same letters in the several figures refer to corresponding parts ofthe instrument.

The nature of my invention consists in adapting a lamp to the upper partof a lantern and allowing the blaze to rise through and above theaperture at the top of the lantern through which the smoke usuallyescapes; and so combining the parts of the instrument that it may atpleasure be made to perform the functions either of a lamp only or of alantern whether the same be effected by means of the raising andlowering of the lamp within the tunic or raising and lowering theexternal tunic itself.

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

I construct a common lamp A, on two opposite sides of which are two pinsor knobs b, 0 by which the lamp may be moved within the lantern. I alsomake a lantern or tunic B, to contain the lamp and of a size sufficientto allow the lamp to move freely within it up and down. The top of thetunic has an aperture 6 which answers the double purpose of allowing thesmoke to escape when the instrument is used as a lantern and also ofallowing the flame to protrude above the instrument when it is used asalamp only. In the sides of the tunic opposite each other I make twovertical slots f, 9, through which the pins or knobs b c of the lampprotrude outwardly to admit of the moving of the lamp.

The upper part of each slot is turned horizontally to allow the lamp tobe turned and supported in the upper part of the lantern or tunic whenthe instrument is used as a' lamp only, as illustrated by Fig. l. Theslots are continued below to the very bottom of the tunic to allow thelamp to be taken out to be cleaned.

Vhen it is desired to change the instrument from a lamp to a lantern thelamp is turned to bring the knobs or pins into the vertical slots andthen the lamp is lowered until it rests upon the base as represented inFig. 2.

The tunic is attached to the base or stand H, by being inserted betweena double collar or rim J, which collar is permanently fixed to the base.The tunic has a rectangular window K in which a piece of mica or othertransparent substance is inserted so as to exclude the wind and allowthe light to pass out when the instrument is used as a lantern.

A modification of this instrument is represented in Figs. 4, 5 and 6, inwhich essentially the same result is produced by the vertical movementof the external tunic L, instead of the movement of the lamp. In thismodified instrument the lamp M, the stem N and the base 0 are allconnected and made in the ordinary manner.

On the opposite sides of the lamp are two vertical grooves T, T,connecting with a horizontal groove T formed around the top of the lamp.

The tunic is open at both ends; the lower opening being a little largerthan the diameter of the lamp so that it can move over and around thelamp. The upper opening is merely suflicient in size to admit the screwcap or box which contains the lamp tubes when the instrument is used asa lamp only.

The inner surface of the tunic is provided with two pins or projections79, g, corresponding in position with the grooves T, T. These pins slidefirst vertically and then horizontally in the grooves when theinstrument is changed from 'a lamp to a lantern as seen in Fig. 5. Thetunic is supported in its elevated position by resting upon the pins, inthe horizontal groove T.

This tunic is supplied with a window similar to that represented in Fig.1.

What I claim as my invention is (Which in effect is analogous) so thatthe The/mode substantially herein set forth of two purposes of a lampand of alantern 1e converting a lantern into a lamp and vice areeffected by one instrument or fixture as versa, said mode consisting inproviding herein above set forth.

and above Which the flame of the lamp is Witnesses:' made to project byraising the lamp by any A. N. LAURENCE, desirable means or lowering thetunic A. MOON.
